TIMOTHY J. SULLIVAN, OF BOW'LING GREEN, KENTUCKY.

DRIER.

SPECIFICATION forming part of Letters Patent No. 326,924, dated September 22,1885.

Application filed July 14, 1884.

To all whom it may concern.-

Be it known that I, TIMOTHY J. SULLIVAN, a citizen of the United States, residing at Bowling Green, in the county of \Varren and State of Kentucky, have invented a new and useful Improvement in Dry-Houses and Apparatus for Increasing the Draft of Furnaces,of which the following is a specification.

My invention relates to improvements in dry-houses and apparatus for increasing the draft of furnaces; and the objects of my improvements are, first, to establish a continuous circuit from the furnace to the atmosphere, wherein the products of combustion shall be separated for the utilization of all substances therein capable of subserving valuable purposes; second, to accomplish this operation automatically; third,to economize fuel; fourth, to accelerate and facilitate the generation of steam; fifth, to accomplish the drying of lumber or other substances by means otherwise valueless; sixth, to discharge the products of combustion to the atmosphere in such purified form as not to be detrimental to public health; and, seventh, to attai these objects with simplicity of construction. Iaccomplish these purposes by the means shown on the accompanying drawings, in which Figure 1 is an elevation of an apparatus embodying my invention, and Fig. 2 is a plan view thereof.

Similar letters designate corresponding parts inboth views.

A is the smoke-stack of the furnace T. A normallyclosed damper, O, therein checks the passage of the smoke to the atmosphere directly, and causes it to traverse the pipe B through the normallyopen valve M. The blower or fan 0 assists this course, and subsequently forces it through pipe E into the dry-house F, where any substances may be placed for the evaporation of contained moisture.

D is a pulley which transmits power received from a belt to the fan.

G is a pipe or stack opening above into the atmosphere, and below accessible to the spent and purified products of combustion which have passed through the drying-chamber.

H is a water tank, which is connected by pipe J, having valve P to control the supply, with the pipe B. The function of this arrange- (No model.)

ment is duplex: first, it obviates deterioration of the metallic blower-frame N and adjacent connections by the exercise of its cooling tendency; second, it prevents the ignition of the heated gases and the possible explosion of the blower, and additionally cools the gases for drying the lumber and other substances to the desired temperature.

K is the boiler.

L is a series of parallel pipes disposed in the same plane on the floor of the dry-house F. They are terminally open to and united by the pipes E G, the former to feed and the latter to discharge the heated air and gas.

R is the furnace-door, and S the ash-pit.

It is obvious that this system affords incidentally a complete spark-arrester.

Owing to the superior draft of the furnace incident to this system, both the quantity and quality of fuel may be less and inferior than ordinarily used.

The operation of my invention is as follows: WVater from the tank H or other source is afforded access to the pipe 13 for the purpose named, and the products of combustion are drawn by the fan 0 into the casing N, and thence forced through pipe E into the dryhouse. By reason of the great length of the latter and the consequent expanse of pipe L approximately all the contained heating power in the gases is eliminated therefrom, being taken up by the pipes and thence radiated throughout the house.

The dry-house may be of any approved construction,and m y system can be accommodated to one already existing.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

1. The furnace having adamper inits stack to deflect all the products of combustion, for the purpose specified, in combination with the dry-house and the pipes connecting them,substantially as shown, whereby said products are utilized in the evaporation of moisture from substances in the dry-house.

2. The tank H, in combination with the pipe B, blower-frame N, valved pipe J, dry-house F, and pipes 13 E L, whereby the tendency of the hot gases to impair said passages in transit is neutralized.

3. The pipes L in house F, in combination IOC with the furnace T,whosestack has a damper, O, to deflect all the smoke, for the purpose set forth, and pipes M E connecting the same.

4. The furnace T, whose stack is provided 5 with a damper, O, for the purpose set forth, blower G, communicating with awater-supply and connections, in combination with the dryhouse F, the pipe system L, the feed-pipe E, and exhauststaok G. 1o 5. The furnace T, having a damper, O, in

the stack, the blower C and the tank H, connected together, for the purpose set forth, in combination with the feed and exhaust pipes E G, the pipes or fiues L, and house F, the

whole co-operating in the manner and relation, I 5

and for the purpose shown and described.
